"DIGITAL-BIO: Living enzyme acts as molecular switch "
Johns Hopkins University researcher Marc Ostermeier described a single-molecule switch engineered from a strand of a living protein�an enzyme. Such molecular switchs could be applied as super-sensitive sensors that detect even a single molecule of a biological warfare agent. Medically, molecular switches have even wider-scale potential, from early detection of hard-to-diagnosis maladies, to "lethal drug" delivery only to cancerous cells.

Lastest Book:

Cognitive computers—cognizers—aim to instill human-like intelligence into our smartphones, tablets and other electronic devices using microchips that emulate the human brain. Dubbed the “Future of Computing” by the NYTimes, one of the “Best Innovation Moments of 2011” by the Washington Post and one of “10 World Changing Ideas” in a Scientific American cover story “A Computer Chip that Thinks” this book reveals how neuroscience and computer science are merging in a new era of intelligent machines light-years beyond Apple's Siri, IBM's Watson.
